That was a solution suggested to me by my Perl/Unix instructor, the revered Dr. Tim Maher. The beauty of it is that it cleans up after itself.

@Amit

That is definitely a better solution. In my defense, when I posted this (3.5 years ago) I didn't "get" that `ssh` could be anything more than a secure remote interactive shell. I've since learned better. : )

The simplest way to do remote diff is as follows:
ssh {remote_host} cat {remote_file} | diff {local_file} -

I think it's worth to add option to pass diff option

if [ $3 = "" ]
then
opt="-b"
else
opt=$3
fi

Recursive remote diff?? Aren't we getting into svn/cvs at that point :)

For recursive diff, you could try using nfs, and pretend they are both local. Obviously using –recursive with diff :-)
NFS wont be so great with your transit costs if you have lots of large files though. Great for LAN environments! – -

What I actually have to write, and soon, is a remote *recursive* diff. Write it, or find one (which is how I got here :)

horst,

You are right, of course. A much better way to do it. I seem to be constantly forgetting how darn versatile ssh is: so much more than just a secure shell.

this will happily overwrite the two files "rdiff.1″ and "rdiff.2″, should they exist in the current directory.

if you really want to diff a _local_ file and a remote one, use something like
ssh remotehost 'cat remotefile' | diff – localfile
…and you don't have to worry about how to create good temporary files
